Transformations of 1-(Oxiranylmethyl)-1,2,3-triazoles into 2-(Oxiranyl­methyl)-1,2,3-triazoles and Alkanenitriles [PDF]

Synlett, 2012
New reactions for the transformation of 1-(oxiranylmethyl)-1,2,3-triazoles into 2-(oxiranylmethyl)-1,2,3-triazoles or alkanenitriles were established. Successive treatment of the substrate with triflic acid and t-BuOH afforded 4,6-dihydro-5-hydroxy-1,3a,6a-triazapentalene derivative.

Click Chemistry: 1,2,3‐Triazoles as Pharmacophores [PDF]

Chemistry – An Asian Journal, 2011
AbstractThe copper(I)‐catalyzed 1,2,3‐triazole‐forming reaction between azides and terminal alkynes has become the gold standard of ‘click chemistry’ due to its reliability, specificity, and biocompatibility. Applications of click chemistry are increasingly found in all aspects of drug discovery; they range from lead finding through combinatorial ...

Synthesis of 1H-1,2,3-triazole-4-carbonitriles as building blocks for promising 2-(triazol-4-yl)-thieno[2,3-d]pyrimidine drug candidates

, 2021
A new synthetic route leading to functionalized 1H-1,2,3-triazole-4-carbonitriles has been developed. A set of 1-aryl-5-methyl-1H-1,2,3-triazole-4-carbonitriles was obtained in high yields from readily available starting 1H-1,2,3-triazole-4-carboxylic ...

Biochemical and in silico inhibition of bovine and human carbonic anhydrase-II by 1H-1,2,3-triazole analogs

Frontiers in Chemistry, 2022
A series of 1H-1,2,3-triazole analogs (7a–7d and 9a–9s) were synthesized via “click” chemistry and evaluated for in vitro carbonic anhydrase-II (bovine and human) inhibitory activity. The synthesis of intermediates, 7a and 7c, was achieved by using (S)-(-
